tixTree pathname [option value...]

The tixTree command creates a new tixTree mega-widget named pathName. The tixTree class is derived from the tixVTree class. It provides a display of hierarchical data in a tree form. The user can adjust the view of the tree by opening (expanding) or closing (collapsing) parts of the tree.
